|“||My name is Thanatos. And I am far from nothing.||”|
In the English release of the manhwa, this character is mistranslated as Tanat.
About 600 years ago, Thanatos came to a gargantuan tower where Demons were emerging into Midgard. He raced to the top of the tower as Surt emerged into Midgard and engaged him in battle. Julianna Lucille and some reinforcements appeared in time to help him keep Surt's magic seals from allowing him to break free from Thanatos' shield. Suddenly, Surt's shield-breaking powers collided with Thanatos' shield and the resulting magic caused them to teleport to the midst of the Sograt Desert. There, the two of them fought for 10 days and nights, the force of their battle splitting the heavens and the earth. On the last day of their epic duel, Thanatos managed to defeat Surt and seal him into the earth, upon which a shrine was built to maintain the seal on Surt.
After sealing Surt, Thanatos disappeared soon after and was never heard from again. Somehow, his ghost has ended up haunting the tower from which Surt used to enter Midgard and the tower henceforth became known as Thanatos Tower. It seems something happened to Thanatos that caused his soul to haunt the tower, as if to guard it from being used to link Midgard to Muspelheim again.
- In Greek mythology, Thanatos was the daemon personification of death. He was a minor figure in Greek mythology, often referred to but rarely appearing in person.
